-| **Total nodes** | Shows the total number of nodes, broken down by state: **Live**, **Offline**, or **Stale**. |
8
-| **Active alerts** | Displays the number of active alerts in a donut chart, with counters for both **Critical** and **Warning** alerts. |
9
-| **Nodes map** | Interactive map with color-coded node statuses and hoverable details. Classify nodes by **Status**, **OS**, **Technology**, **Agent version**, **Replication factor**, **Cloud provider**, **Cloud region**, or **Instance type**. Configure color-coding by **Status**, **Connection stability**, or **Replication factor**. |
10
-| **Data replication** | Two bar charts: (1) Node roles as **Parents**, **Children**, and **Standalone**. (2) Replication factors as **None**, **Single**, and **Multi**. |
11
-| **Alerts overview (last 24h)** | Two views of alert activity: (1) Bar chart showing nodes with the most alerts in the last 24 hours. (2) Table of the top alerts, with instance name, number of occurrences, and duration (in seconds). |

-| **Netdata Assistant shortcut** | Button to start a conversation with the Netdata Assistant for help and troubleshooting. |
13
-| **Space metrics** | Displays key statistics: **Metrics collected**, **Charts visualized**, and **Alerts configured**. |
14
-| **Data retention per node** | Bar chart showing the number of nodes grouped by retention period. |

+- The Home tab provides critical infrastructure visibility through real-time node status, alert trends, and deployment topology.
20
+- The **Parents/Children/Standalone** breakdown shows your streaming architecture at a glance, helping you understand your data collection hierarchy.
21
+- The **Data replication** metrics indicate how many nodes have no replication, single replication, or multi-replication for high availability.
22
+- Use the **Nodes with the most alerts** chart to quickly identify problematic hosts requiring immediate attention, and the **Top alerts** table to spot recurring issues that may need alert tuning or infrastructure remediation.
